A Location Guide for Rock Hounds in the United States
GEORGIA
Georgia’s nearly 59,000 square miles makes it the largest of the Atlantic seaboard
states. It is situated at the southern end of the Appalachian chain of mountains. These
ranges extend into the northeast corner where Brasstown Bald, a part of the Nantahala
Mountains achieve the highest elevation in the state at 4,784 feet.

Georgia
Beginning in the northwest, where the Lookout and Sand mountains loom over rich
agricultural valleys, Georgia easily divides into five major physiographic provinces, each one
formed during different geologic ages and under varied conditions: the Cumberland Plateau,
the Appalachian Valley, the Appalachian Mountains, the Piedmont Plain (about 30% of the
state), and the Atlantic Coastal Plain. Thus rocks of every geological age are exposed
somewhere over the state’s varied surfaces. The upland northern counties are heavily
forested with hardwoods, merging into other forests of stately pines on the Piedmont.
Beneath the highland forests lie some of the oldest crystalline rocks in the East, both
igneous and metamorphic, strongly mineralized and dotted with once-rich abandoned mines.
Dividing the stratigraphically complicated Piedmont Plain from the coastal lowlands
in the Atlantic Coast Fall Line, so named from the falls or rapids in rivers at places where
they pass from the Piedmont crystalline rocks into softer and less resistant formations of the
Coastal Plain. This Fall Line extends southwesterly across the state roughly on a line
connecting Augusta, Milledgeville, Macon, and Columbus.
The first real Gold Rush in America occurred in Georgia following two simultaneous
discoveries of Gold by Negro slaves in 1828, one on the Lovelady place near Loudsville in
White Co. and the other on the Bear Cr. near Dahlonega in Lumpkin Co. Not only was
placer and lode gold found in abundance here and elsewhere, but the early miners and
prospectors panning the regional stream gravels discovered Diamonds, the largest a pale
yellow crystal of 4½ carats picked up near Morrow Station in Clayton Co. in 1887. Since
then, many fine diamonds have been found and are still being occasionally washed out of
gold pans. Many other gem crystal species occur in pegmatite exposures, such as
Aquamarine, Beryl, some Ruby-red Corundum, Spodumene and Topaz.
Georgia has been actively prospected for gold since colonial times, and the modern
gold panner should concentrate his efforts in the known gold-bearing areas. Lode deposits
usually consist of Quartz veins in solid rock, while placer deposits occur in a great many
regional streams. Much of the colors are Fluor Gold, too fine to be retained in any
commercial operation. The two most important gold belts include  the Dahlonega Belt that
extends from near Tallapoosa northeastward through Dahlonega Co. and Rabum Co., and 
the McDuffie County Belt extending through portions of McDuffie, Warren, Wilkox, and
Lincoln counties. In many places, but most notable in the lode gold districts, numerous other
colorful minerals occur in association with Gold, such as Chalcopyrite, Galena, Pyrite,
Pyrrhotite and some Sphalerite.

lesser extent, but all are composed of basalt.
Almost the only minerals present on any of the islands are sands, some gravel, and
limestone, including deposits of calcareous algae and the skeletons of stony corals. In the

Idaho
IDAHO
With an oddly configured Panhandle shape, Idaho reveals a varied topography. The
central and northern portions are extremely rugged, encompassing the massive Sawtooth
and Salmon River mountain systems, with many lakes, and snow-laden peaks that rise more
than 12,000’ high. The mountains have been extensively prospected and mined for Copper,
Gold, Lead, Silver and Zinc. As a Gold producing state, Idaho ranks 9th in America. Many
abandoned mining ghost towns dot the mineralized areas.
The mountainous nature of Idaho led early prospectors from Virginia City, NV, and
Bannonk, MT into its labyrinthine watersheds in search of Gold and Silver. Idaho’s
mountain systems are the result of enormous batholithic intrusions that took place during
the Laramide revolution some 70 million years ago. Known to geologists as the Idaho
Batholith, this granite mass covers from 16,000 to 20,000 square miles and is probably the
largest and best-known such geological phenomenon in America.
The earliest known Gold discovery in Idaho was an auriferous sandbar along the
Pend Oreille River in 1852. Then in 1860 Captain E.D. Pierce found Gold near what became
the town of Pierce in Clearwater Co., with other rich placers soon being mined at Elk City,
Orofino, Boise Basin, Florence and Warren. Although many of the richer placers were
exhausted by 1870, the following half-century led to intensive exploration for lode Gold
deposits. Most of the state’s Gold came from lode mines after 1900.
In addition to the basic and noble metals, produced in astonishing abundance, Idaho
provided large amounts of strategic minerals of inestimable value to the emergencies of
World War I and II. Potentially, at least, the Panhandle State ranks above all others in
America in the importance of its mineral resources. Aside from the commercially valuable
minerals, the state provides an unusual abundance and variety of gemstones, gem crystals,
silicified woods, and other mineral items highly valued by collectors occurring throughout
the state in many more localities than enumerated here.

ILLINOIS
Known as the Prairie State, Illinois exhibits a length of 378 miles and a width of 210
miles, with its 56,000 sq. mi. sloping slightly to the southwest. Containing more than 275
rivers, the state is bounded along ¾ of its circumference by navigable waters, primarily the
Ohio and Mississippi rivers. The highest elevations are the Mounds along the northern
borders, rising only to a altitude of 900 to 1,000 feet above sea level.

Though well endowed with fossils, Illinois has little to offer gem and mineral
collectors, even though the state produces more sandstone, silica sand and Fluorspar than
any other state in America. Most specimen collecting is done in the Lead-Zinc mining dists.

Fossil hunters are well aquatinted with the famed Coal Measures so often mentioned
in Illinois geology. These measures constitute the Upper Carboniferous system of repeated
alterations of sandstone, shale, bituminous slates, thin bands of limestone, and seams of coal
usually underlain with clay. In these coal seams the collector may often find Marcasite and
Pyrite. The measures are 1,200 to 1,400 feet thick in the south, grading to 600 to 800 feet
thick in the north.

INDIANA
The geologic formations of the Hoosier State are predominantly sedimentary of
Ordovician to Pennsylvanian age, that is, from 550 to 330 million years ago, with many
Silurian exposures (430 million years old) outcropping east and west across the state in the
latitude of Newton and Adams counties. The oldest formations occur in the eastern counties,
with the youngest rocks appearing in the southwest. The most important formation is the
Mississinewa shale, lowest of the Niagaran series, and loaded with fossils. There are no
igneous or metamorphic rock outcrops in Indiana.
181
Indiana
The four great periods of glaciations of the Pleistocene period successively smoothed
off the irregularities that may originally have existed in the northern counties. The debris
pushed ahead by the ice was dropped throughout the central agricultural area, blanketing
nearly five-sixths of the state to considerable depths in places. This morainal detritus
contains what few gems and minerals there are in Indiana, mainly agate, jasper,
fossilized corals and petrified wood. Copper nuggets have been found scattered over
eighteen counties between the eastern and western boundaries and as far south as
Vanderburgh Co., brought down by glaciers from the Lake Superior Copper regions.
Similarly, cubes of Galena also transported by the ice have given rise to many false reports
and legends of Lead mines in Indiana.
The moraines of thrice glaciated Morgan Co. yield quartz gemstone pebbles, some
Topaz, and now and then bits of Corundum. This and adjoining Brown Co. have also
produced an astonishing 30 Diamonds over the last century. These glacial-drift gems were
found during gold panning operations in the regional streams that produced small quantities
of Gold.
In the central and southern counties are many coal mines containing usual
associated mineral of Goethite, Marcasite, Pyrite, Selenite and Sphalerite. Regional
limestone quarries produce some gemmy Apatite, Calcite, Glauconite, Marcasite, Pyrite
and Quartz. Now and then Barite, Celestite, Dolomite and Siderite can also be found in
regional limestone quarries.

A Location Guide for Rock Hounds in the United States
IOWA
Iowa is primarily a prairie state of moderate relief, with low hills in the unglaciated
northeastern section and rich, rolling tablelands interrupted by many streams elsewhere.
The highest point in the state is a knoll rising 1,675’ above sea level west of Sibley in the
northwestern corner of Osceolo Co. The present surface features are a result chiefly of the
uneven mantling of preexisting indurated rocks by glacial drift, since all of Iowa was
included within the region of the Pleistocene glaciers.
For much of the Mesozoic era, and especially during the whole of the Cretaceous
period, Iowa lay under a broad shallow, epicontinental sea; therefore, the subsurface
formations are dominated by sedimentary deposits. Throughout the state almost any road or
railroad cut, erosional gully, cut bank, stream bank, quarry, or other excavation, however
shallow, is a promising place in which to look for Quartz family gemstones and fossils.
Indeed, beautifully colored silicified colony corals and stromatoporoids are commonly
encountered, capable of being cut and polished into unusual gemstone art objects. These
gemmy fossils occur principally in Devonian limestone exposures which outcrop over much of
Iowa, being most typical and best know around Iowa City.

KANSAS
As a mineral producing state, Kansas is seldom appreciated even by its own
residents. Economically, the mineral industry is second only to agriculture, and the state
outranks most others except California in its mineral production. However, the mineral
wealth derives primarily from Coal, Zinc, Lead, Gypsum and volcanic ash, in this order, now
being superseded by great new reserves of oil and natural gas. As a collector, Kansas is
likely to be bypassed by the traveling rock hunter, although in-state collectors find many
interesting specimens worthy of being added to their collection.
Western Kansas comprises the rather rugged semiarid Great High Plains. The land
surface is thinly covered by Pleistocene and Recent gravels, with extensive Pliocene lavas
capping the buttes and mesas. Few gemstones, but an enormous variety of fossil vertebrate
bones weather from the cut banks and washes.
About 1,7500,000 years ago northern Kansas was invaded by the Kansan glacier,
second of the four Pleistocene ice advances, as far south as the Kaw Valley and the Little
Blue river. In this region’s gravel pits, quarries, and morainal deposits can be found a
variety of glacial drift gemstones. By contrast, southeastern Kansas constitutes an
extension of the Ozark Plateau into what is termed the Tri-State District, where Kansas,
Missouri and Oklahoma join boundaries. This district is interesting to the mineral collector
because of its many highly productive Zinc and Lead mines. Dumps rising 100’ high are
know as chat mountains and produce abundance of desirable mineral specimens of Barite,
Calcite, Chalcopyrite, Cerussite, Dolomite crystals, Galena, Pyrite and Sphalerite.
To be noted on geologic maps is the widespread Ogallala formation (Tertiary),
embracing the counties of Clack, Ellis, Logan, Ness, Rawlins and Wallace. In this formation
are found dendritic opal, white translucent opal as irregular masses or nodules, opalized
bones, and much petrified wood. From the western Cretaceous chalk beds exposed in the
counties of Cherokee, Logan, Norton and Phillips, one can gather colorful gemmy chert and
jasper. Anderson, Brown, Chase and Franklin counties yield fine crystals of Barite. In
general, the surfaces of draws, washes, and sandhills of all the western half of Kansas
produce agate, chalcedony, chert, jasper and petrified wood, although very little is

KENTUCKY
Minerals are the major contribution to the Blue Grass State’s economy. These
consist mainly of coal, limestone, fluorspar, rock asphalt, gravel and sandall products of
sedimentation. The state is part of a very old land surface, lying within the eastern uplifted
Appalachian Plateau and the westerly Interior Low Plateaus. During most of the Paleozoic
and Mesozoic eras, Kentucky lay beneath the sea, and thus its rock formations are
predominantly sedimentary shales, sandstones, limestone, etc., with almost no igneous or
metamorphic intrusions.
The rugged hardwood timbered Cumberland Plateau that comprises part of eastern
Kentucky rises to 4,100’ in Big Black Mt., highest of numerous peaks that straddle the
Virginia border in the range of the same name along the boundaries of Bell and Harlan
counties. This plateau breaks toward the Bluegrass heartland in the Pottsville Escarpment,
marked by a belt of rounded shale hills known as the Knobs. To the west in the low
Mississippian Plateau, a region of rocky hillsides denotes an extensive area of underground
streams which have carved such great caverns as the famed Mammoth Caves in the
limestone sub-strata.
The region lying east of the Tennessee River emerged from the Paleozoic seas toward
the close of the Mississippian period some 340 million years ago. Outcropping rocks in this
region range from middle Ordovician to the Pennsylvanian, containing few collectable
minerals and gemstones but great amounts of fossils. Nevertheless, wherever the Fort
Payne and Warsaw formations of the Mississippian Period outcrop, gemmy geodes appear
abundantly. These interesting nodules are found in many sizes from walnut to beach ball.
Some contain beautifully banded chalcedony, while others have interiors lined with crystals
of Calcite, Celestite, Fluorite, Goethite, Pyrite, and Quartz. The most productive area for
geodes surrounds the Bluegrass, southward into Tennessee. Throughout this considerable
region, investigation of creek and stream beds & banks, runs & rills, rd. and RR cut banks,
excavations, almost always reveals an abundant supply of geodes.
The lands lying west of the Tennessee R., known as the Purchase Region, did not
emerge from the sea until Tertiary times only 40 to 50 million years ago. This region
remained for long ages as the head of a great embayment extending north from the ancient
Gulf of Mexico, thus receiving largely estuarine deposits. Cretaceous and Tertiary formation
are developed principally in the Jackson Purchase area, while Pleistocene alluvium occurs
plentifully in the valleys of western Kentucky and along the Ohio R. and its tributaries.

LOUISIANA
Louisiana, lying in the lower Mississippi River Valley has only in recent times been
elevated above the surface of the ancient Gulf of Mexico. The land has a maximum elevation
above sea level of 500’, sloping gently southward from the Arkansas line with an average
elevation of 400’. A very low dividing ridge runs along centrally through Louisiana,
separating the Ouachita and Red river drainage systems east and west. Along these two
rivers the flood plains and secondary bottoms (or hammocks as they are locally called), form
a very minor topographic feature in the generally monotonous landscape.
The state lacks gemstones and minerals generally, Brown Hematite and Limonite
occur in Tertiary sands in numerous deposits in the northwestern parishes of Bienville,
Bossier, Caddo, Claiborne, Lincoln and Union. The northern counties also reveal various
exposures of hard limestone, Gypsum, Salt and marl in separated exposures of Cretaceous

Louisiana
strata. Tertiary formations (Eocene and Oligocene) outcrop in nearly every parish to yield
petrified wood (mostly of hickory, oak, poplar and palm). large silicified logs have been
found in De Sota Parish. The whole history of the Tertiary laminated sands and lignitic
shales is that of gradually receding sea, too recent to allow formation of the type of minerals
and gemstones most sought after by collectors.

Maine
MAINE
The topography of Maine was sculptured by Pleistocene glaciers two miles thick in
places, eroding the original Tertiary land surfaces right down to bedrock. Thus, the state
rests on its ancient foundation of limestone, sandstone, and shale. The generally
mountainous, heavily forested western region slopes northward to the St. John River Basin
and eastward toward the Penobscot River. Receding glaciers dammed the valleys with long
drift ridges to form some 2,200 lakes. In the more than 5,000 rivers and streams, gravel
beds yield up many interesting gem and mineral specimens.

A Location Guide for Rock Hounds in the United States
Where deep-seated earth forces caused molten granite to intrude the basal
sedimentary rocks and recrystallize them, many valuable mineral and gemstone deposits
were formed. Indeed, the mineral wealth of Maine is notable, especially for the wide variety
of gemstone minerals which occur in the state’s extraordinary pegmatites. These dikes are
essentially coarse grained concentrations of feldspar and quartz, developed during the
closing stages of widespread granitic intrusions through the foundation rocks. The great
glaciers exposed most of the dikes; easily traceable as pod-shaped or sheetlike bodies ranging
from a few inches to more than 4,000 feet in length.
211
Maine
The Maine pegmatites have been mined for more than a century for potash feldspar,
along with occasional production of Quartz, sheet Mica, Beryl, Spodumene, and other
industrial minerals. Substantial quantities of semi-precious gem crystals have made the
Maine pegmatites world famous, because of the high gem quality of their Aquamarine,
Beryl, Garnet, rose Quartz, Spodumene, Topaz, Tourmaline, and many other
gemstones. Perhaps nowhere in the world is there an area of comparable size productive of
such an array of quality gems as Oxford County. Here, in particular, the Newry mines near
Rumford and the Mica mines near Paris are a collector’s Mecca.
A good field reference with maps, A Collector’s Guide to Maine Mineral Localities is
available at the Maine Geological Survey.

Maryland
MARYLAND
Divided by the drowned canyon of the Chesapeake Bay, Maryland is characterized by
three strikingly different geological provinces. The Coastal Plain extends westward from the
present margin of the continental shelf to the Fall Line, passing through the cities of
Baltimore and Washington DCa flat, almost featureless sea level plain underlain by
unconsolidated clays, sands, and gravels of the Mesozoic and Cenozoic age dipping at a low
angle toward the southeast.
The Piedmont Plateau forms the central part of Maryland, extending westward from
the plains, or Fall Line, to the east side of South Mountain. This region is an undulating
upland with a maximum elevation of 1,000 ft., formed of ancient, intricately folded and
gently faulted strata thoroughly metamorphosed by intense crushing and extensive igneous
intrusions. In the west and north the Piedmont rises to the Blue Ridge and the hills of
Pennsylvania.
The Appalachian Province spans the region between South Mountain and the West
Virginia border, divided into three main districts: the Blue Ridge, the Greater Appalachian
Valley and the Allegheny Plateau. Here, in the extreme southwestern corner of Garrett Co.
almost on the West Virginia line, rises the highest point in Maryland, Backbone Mt., 3,360
ft. above sea level. This province provides the gem and mineral collector with some excellent
materials, derived from a series of metamorphosed volcanic flows and tuffs. Replacement
mineralization yields some relatively rare mineral species, while vugs and cavities often
contain interesting secondary minerals.
From the gem collector’s point of view, the most rewarding gemstones occur in the
serpentine and Chromite deposits that are widely distributed through five northern
counties (Cecil, Hartford, Baltimore, Carroll and Frederick) in a region locally known as the
Barrens because of the stunted nature of its vegetation. Here a gemmy serpentine called
Greenstone has long been quarried for building stone and railroad ballast. The associated
Verde Antique, laced with twisting white veinlets (the serpents that originally gave
serpentine it’s name), is greatly valued for its decorative nature. Another metamorphic type,
locally called Baltimorite, is valued by collectors a cutting material because of its pale blue
green color and compact fibrous texture.
230
A Location Guide for Rock Hounds in the United States
Associated with these deposits are Picrolite, a rare form of foliated blue green
serpentine closely resembling asbestos, and Brucite, a silvery mineral with green and red
inclusions in a fibrous matrix. Here also occurs a gemmy, jadelike serpentine called
Williamsite, much valued by collectors. Indeed, because of its apple green color and
translucencency, Williamsite ranks among the most sought after gemstone in Maryland. All
these gemstones occur in the famed State Line Pits that straddle both sides of the MarylandPennsylvania border, especially in Cecil Co., MD, from the Susquehanna River eastward to
the Delaware line. Other associated gemstones and minerals include clear and smoky
Quartz crystals, jasper, Olivine crystals, Enstatite, Tourmaline, Rutile (in the form of
red lustrous, prismatic crystals), Vesuvianite, light green massive Talc useful for carving,
pink to purple Kämmererite, Magnetite, Hydromagnesite, and Deweylite (a hydrous
magnesian silicate), with apple green Genthite representing a nickel replacement of
magnesium.
Following the Civil War, Maryland was extensively prospected for gold. Gold Quartz
ores were found in the Piedmont, and although mining did not prove profitable, one can still
pan for colors in the regional stream gravels. For years Maryland was a leading producer of
copper, lead, iron, manganese, molybdenum, titanium and zinc, while pegmatites
outcropping in the eastern Piedmont have been abundantly mined for Mica and feldspar.
Much asbestos has also contributed to the mineral economy of the state.
Visiting gem collectors to the State Line Pits must necessarily include both the
Maryland and Pennsylvania mines. At least a hundred mines and prospects surround the
crossroads towns of Cecil Co., MD, west to east from the Susquehanna River, of Pilot,
Oakwood, Rock Springs, Goat Hill, Sylmar and Calvert, while almost as many other
workings on the Pennsylvania side of the boundary surrounding the communities of Pleasant
Grove, Wakefield, Lyles, Wrightsdale, Nottingham, Chrome and White Barrens. Since all
collecting areas are privately owned, permission to collect is important.

MASSACHUSETTS
The Connecticut River Valley divides Massachusetts, with its mean elevation of 500
ft. above sea level, into an eastern coastal plain, marked by short, swift rivers, and a western
region of minor uplands that rise toward the Berkshire Hills in north central Berkshire Co.
These hills, which climax in Mt. Greylock at 3,491 ft., are but the glaciated remnants of an
Ordovician mountain building overthrust of such magnitude that the whole of New England
was narrowed by several hundred miles. The crumpling of Cambrian and Ordovician
sedimentary strata raised up the Taconic Mountain range, which borders the western part of
the state.
The Connecticut River Valley is characterized by sill type exposures of vast basalt
flows. Gas cavities in the basalts often contain such collectable items as agate, chalcedony,
and geodes which are sometimes lined with excellent amethysts. Although extensive
limonite iron ore beds of considerable economic value occur in the West Stockbridge area of
Berkshire Co., and coal is found in Norfolk Co., the mineral industry of Massachusetts is
definitely secondary in importance to industrialization.

Michigan
MICHIGAN
Michigan is separated into two distinct parts by the Ice Age waters of Lake
Michigan. In the far northwest the Upper Peninsula extends from the Wisconsin boundary
to front onto southwestern Lake Superior, where a long arm, the Keweenaw Peninsula,
curves into the great body of fresh water. This remote region is the northern woods country,
known facetiously as a land with ten months winters and two months sledding. Here,
enormous Copper deposits were early stripped of great masses of native metal, as well as
unbelievably rich ores, with active mining continuing right up to the present.
Mined primitively by prehistoric Indians for nuggets of Native Copper that could be
hammered into ornaments, the deposits also produced many such huge unworkable masses
as one single nugget that weighed more than 420 tons, when eventually broken up and
excavated by the miners. The most productive mines and gem rich dumps occur in the
Copper Range, about 25 miles long, extending from Painedale in Houghton Co. to Mohawk in
242
A Location Guide for Rock Hounds in the United States
Keweenaw Co. However, virtually every community shown on maps of the Upper Peninsula
is a mining center and consequently of interest.
Also occurring in the Upper Peninsula are almost equally important and extensive
bodies of high grade Iron ore. Where the copper mine dumps yield up very many gemstone
materials and colorful ore minerals, the iron dumps are more gemologically noted for a
rather extraordinarily attractive gemstone known as the Kona Dolomite. This impure
dolomite is really a breccia of silicified algae of Huronian age, 2½ to 3 billion years old. The
fossil algae grade into chert and quartzite in various shades of pink, orange, brown and red
intricately laced with steel-black Hematite.
The gem and mineral collector will find that there are two different types of
collecting to be considered in Michigan: Hunting along the State’s lake beaches for
gemstones (especially Lake Superior type agates) and working over almost countless iron
and copper mine dumps. The Keweenaw Peninsula, especially in Houghton and Keweenaw
counties, contains the richest copper mines. At the same time, the Lake Superior beaches
surrounding the peninsula are rich in agates, with Thomsonite and Chlorastrolite
occasionally encountered.
243
Michigan
The agates are generally small but richly banded and quite colorful. An occasional
large nodule may be found, as witness the 17 lbs. prize reported from Keweenaw Point. They
represent a subvariety of the Lake Superior type, differing in their primary color, are brown
with generally tone-on-tone bands and a tendency toward greater opaqueness. The
associated Thomsonite is a pastel pink and green cutting material (perhaps a pink
Prehnite) occurring in radiating sunburst patterns. The Chlorastrolite, locally termed
greenstone, is a rare Zeolite gemstone. Along with these sought after materials, the
collector is also likely to find waterworn samples of chalcedony, jasper, gemmy chert and
Adularia orthoclase.
The copper dist. mine dumps are especially interesting to the collector. The dumps
contain abundantly the unusual assortment of blue-green-purple ore minerals plus frequent
nuggets of native Copper & Silver and a naturally occurring combination locally named
half-breeds. In addition occur such other gemmy materials as Ankerite, Calcite crystals
(many with raw copper inclusions), Domeykite, Epidote, Laumontite, Prehnite and
Tenorite with Chrysocolla. Indeed, the Keweenaw Peninsula mines and beaches,
including Isle Royale, afford at least 60 desirable gemstone and minerals.
The Lower Peninsula, constituting most of Michigan, also contains a considerable
mineral wealth, but mainly in such less spectacular products as Gypsum, sandstone,
limestone and salt. One exception to the general paucity of gemmy materials is the locally
abundant occurrences of the famed calcified Hexagonaria coral know as Petoskey stones.
These gemmy fossils are most abundant along the beaches of Traverse Bay from Petoskey in
Emmet Co. to Charlevoix in Charlevoix Co., a stretch of 14 miles, as well as in the regional
gravel pits and quarries back from the beaches. Elsewhere in the lower Michigan, quarries
and gravel pits yield up crystals of Calcite, Celestite, Dolomite, Pyrite, Sphalerite and
various kinds of quartz family gemstones.

MINNESOTA
This nearly level and most northern state of the continental United States is a broad
glaciated plain with an elevation of 1,000’ to 1,500’ above sea level. More than 11,000
Pleistocene ice-scoured basins are filled with sparkling lake waters, remnants of the great
Pleistocene lake Agassiz, 700 mi. long by 250 mi. wide, that covered much of northwestern
Minnesota some 10,000 years ago, and lesser lakes elsewhere that impounded the glacial
melt waters as the ice retreated northward. Only the extreme southeastern corner of the
state, in the eastern parts of Winona and Houston counties escaped the Ice Age glaciers.
Thus immense deposits of glacial drift, consisting of till, gravels and stratified sands and
clays dominate the state’s surface topography.
The only section that might be termed at all mountainous lies in the northeastern
triangle. Here the Lake Superior hill ranges (Sawteeth, Mesabi, Cuyuna, Gunflint, Giant’s
Range, Vermillion) rear a few worn and rounded peaks to the elevation near 2,000’ above sea
level, or 500’ above the surrounding countryside. Even these ranges from which much of the
world’s richest Iron ores have come are heavily drift covered.
249
Minnesota
By far the most widely distributed and popular gemstone, for which Minnesota is
especially noted, is Lake Superior agate, distinguished by its translucency, rich glowing
colors, and fine parallel banding. Lake Superior agate are usually found in sizes from ½” to
2” in dia. (with an occasional nodule weighting several pounds) and containing high grade
gem quality throughout. Three forms are recognized: eye agates, an onyx-like banded agate,
and fortification agate that resembles the famed Fairburn agates of South Dakota.
Practically every glacial moraine of drift deposit, every gravel bank and stream bar, every
lake beach, quarry, excavation, and gravel pit in the entire state yields up a surprising
abundance of these eagerly sought after gemstone.

MISSISSIPPI
Although its surface is everywhere characterized by Cretaceous to Tertiary
sediments less than 100 million years old, Mississippi lends its name to a 25 million year
long depositional epoch in American geology that began 355 million years ago during the
Lower Carboniferous period. Like other adjoining states that also anciently lay beneath the
extended Gulf of Mexico, all of the state’s formations were laid down under salt water as the
gulf slowly receded southward from its northern-most Paleozoic reaches below the present
Ohio River Valley. Such sedimentation is still actively going on, wherever rivers discharge
their burdens of mud, silt and sand into the modern Gulf of Mexico.
255
Mississippi
The sixteen counties that embrace most of north-central Mississippi are part of a
very low North Central plateau, underlain by Eocene formations of 60 million years ago. In
the two most northeastern counties of Alcorn and Tishomingo, the Tennessee River Hills
achieve maximum elevation of 700’, while the general statewide surface is at or near sea
level.
Few gemstone localities exist in Mississippi. However, the state yields a great
abundance of fossils of many geologic ages. Petrifactions occur in the northeastern and
central counties, where the preservations occur in unattractive Iron oxide. In some area the
state’s fossil trees contain lovely, small water-clear Quartz crystals, as well as drusy quartz
linings of cracks and fissures. Considerable quantities of this fossil wood weather out of
exposures of the widespread Lafayette formation, with smaller quantities occurring in the
Wilcox and other Tertiary sediments. A considerable petrified forest area, once noted for its

Missouri
MISSOURI
Missouri lies in the greater Mississippi Basin and provides excellent exposures of a
wide range of Paleozoic formations from the Cambrian period through Permian. Cretaceous
marshes and swamp forests left many coal deposits throughout the state, while
epicontinental seas laid down thick beds of sand and limestone. The youngest of the
stratified rocks are the Cretaceous Coal measures which comprise the northwestern twofifths of the state, while the south-central one-third is occupied by the oldest rocks, those of
the great Magnesian Limestone series. However, from the north extending as far south as
the Missouri River, approximately, a thick mantle of Pleistocene detritus derived from the
glaciation of more northern regions overlies the more ancient structures.
The state’s chief topographical feature is the Ozark Uplift, a broad plateau with
gentle slopes rising to 1,500’ above sea level and extending entirely across the southern part
of Missouri, bordered on all sides by deep grooves and narrow gorges. This Ozark region,
containing rock formations of several different geological ages, is one of the most heavily
mineralized areas in the world. Many great mines and pits enrich the state’s economy with
their production of Barite, clay, Hematite and Lead & Zinc with Silver as a by-product.
258
A Location Guide for Rock Hounds in the United States
Missouri’s mineral wealth is found three
main regions: Coal in the west and north-ventral
counties, Lead in the Tri State district (in the
corner of Missouri, Kansas and Oklahoma) and
the New Lead district in the Viburnum Trend of
southeastern counties centered at Viburnum,
MO.
A considerable variety of gemstones also
occur in Missouri. Typical Lake Superior agates
are abundant in the glacial drift deposits of
Gentry, Davies, Grundy and Livingston counties,
along with agatized coral and bone,
chalcedony, jasper and petrified wood. All
along the Mississippi River, which is the eastern
boundary of the state, gravel operations yield an
endless supply of fine, high quality agates and
other quartz family gemstones. In Clark Co.,
around Kahoka, exposures of the Warsaw
formation disgorge great quantities of geodes
which differ from the Iowa type in that more of
them are hollow and lined with brilliant crystals
of pink Calcite, Fluorite, Goethite, Millerite
and Pyrite. The regional stream beds contain
many such geodes, which are constantly being
Missouri New Lead District Mines
weathered out of surrounding ledges. Elsewhere,
an interesting and colorful gemmy chert, locally
called Mozarkite, makes rock hunting productive in such central Missouri counties as Benton
and Hickory, while another variety of cutting-quality chert is well known from McDonald Co.
Gemmy crystals of Crested Barite are much sought after in St. François and
Washington counties in eastern Missouri, while directly across the state in Jasper Co.,
gorgeous crystals of Lead and Zinc minerals make dramatic cabinet specimens. These
crystals occur abundantly deep in the Joplin and Tri-State area mines: brilliant cubes of
Galena, a distinctive bronzy cockscomb Marcasite, delicately curved flesh-pink colored
Dolomite, honey-colored Calcite, and the ever-popular deep ruby-red massed crystals of
Sphalerite. Because of their high mineral value, such crystallizations, including iridescent
Chalcopyrite, are not thrown out on the many extensive mine dumps but must be
purchased locally as cabinet specimens.

MONTANA
Montana was named from its mountains. Dominated by the complex Rocky Mt.
system that originated with the Laramide revolution to close the Mesozoic era and initiate
the Cenozoic, western and southwestern Montana carries the Continental Divide on the
rugged granite shoulders of the Bitterroot Range that is the state’s western boundary. Every
few years, earthquakes smashing across the mountain regions remind us that the mountainbuilding forces are still dramatically active.
Early prospectors, who followed trails pioneered by Lewis and Clark in 1805 and the
fur voyageurs of subsequent decades, came as losers from the California gold fields, They
discovered enormous new sources of mineral wealth in Gold, Silver, Lead, Copper,
Manganese, and Zinc, causing Montana to become known primarily as a mining state.
Montana also has another kind of mineral wealth in Montana moss agate and Sapphires,
contributed to the state’s high placement in every gem and mineral collector’s places to visit
list.
Montana is seventh in the list of America’s gold producing states. Many placers were
discovered in Powell, and Beaverhead counties. Many other rich placers were also found in
Alder Gulch where Virginia City (1864) now slumbers as the county seat of Madison Co.
Such placers, which produced nearly half of the state’s total gold, were most active prior to
1870 but continued pouring out the yellow metal until W.W.II. Today, panning for gold is a
major summer hobby.
Inauspicious showings of colors in an iron gossan covering a major butte in Silver
Bow Co. in 1864 created a modest Gold and Silver camp known as Butte. But when the
underlying Copper ores were penetrated in 1880, Butte erupted into the greatest Copper
center on earth, adding more than $2 Billion to the states economy. The Copper brought the
railroads to Montana and greatly aided the settlement of the state.
Although for nearly a century Montana made exciting economic and political news
with its metal mines, late comers began making Montana world famous for Montana moss
Agate. This gray chalcedony nodules shaped like Idaho potatoes occur in the gravel bars and
adjoining benches along the Yellowstone R. for some 250 mi. eastward from Billings to Miles
City, with numerous side streams out of Wyoming contributing a minor supply. This
extraordinary gemstone consists of unusually translucent chalcedony laced with
275
Montana
Manganese Dioxide against a background often of brilliant red carnelian. When sliced, the
nodules reveal delicate landscape scenes of mountains, forests, trees, bushes, ferns, lakes,
clouds, and figures.
Two other highly desired gems, purple Amethyst and cornflower blue Sapphires,
are notable from Montana. The Gold mines of Jefferson Co., E of Butte, produce high quality
Amethyst as a by-product, along with lovely water clear Quartz. The Sapphires come
mostly from the stream gravels of Lewis and Clark Co., out of Helena, although other
western counties also produce the blue gem Corundum.
